On the impulse response function for water waves generated in fluid of constant depth

The paper deals with the problem of surface gravitational waves generation in fluid of constant depth. The main goal of the investigations is to find the impulse response function for the generator-fluid system. Two independent formulations of the original task are considered. These two formulations lead to different formulae describing the same characteristic feature of the system. One on these formulations however is more advantageous then the other one since it takes shorter time of computer calculations.
